HMX COSMIC PURPLE LINEAR Switches

The HMX Cosmic Purple Linear is a mechanical keyboard switch designed for enthusiasts seeking a unique sound profile and smooth performance. It stands out as the first HMX switch to feature a full POM (Polyoxymethylene) housing, paired with a distinctive LY stem, resulting in a clacky, higher-pitched sound signature that sets it apart from other switches in its class.

Construction and Materials

This switch utilizes HMX's new full POM housing mold, offering durability and a refined acoustic experience. The combination of POM for both the top and bottom housing, along with an LY stem, ensures a smooth keystroke and a vibrant sound spectrum. Unlike many other POM and LY stem switches that produce a deep, "thocky" sound, this model delivers a crisp, clacky tone with a touch of audible scratch for added character.

• Top Housing: POM (Polyoxymethylene)
• Bottom Housing: POM (Polyoxymethylene)
• Stem Material: LY blend
• Mold: Brand new, proprietary design

Sound Profile

One of the defining features of this switch is its unique sound. Thanks to the innovative molding design and LY stem blend, it produces a super clacky and higher-pitched tone, diverging from the deeper sounds typical of similar switches. The full POM housing broadens the sound spectrum, making each keystroke feel full and vibrant. An intentional, slight audible scratch is present for users who appreciate tactile feedback in the sound.

• Clacky and higher-pitched sound
• Full and vibrant acoustic profile
• Subtle, intentional audible scratch
